In shanghai, four plant factories are located outside the caucasian building. Push the door in. Strawberry clears the noodles. There are no storms and no sunlight, and a strawberries crop using limited space to break high-energy consumption is taking place between inches。
The finals of the fifth multi-agricultural science and technology competition and the inauguration of the plant plant were held at the shanghai agricultural science and technology festival. The four teams that broke into the finals were pioneers in deep-tilled vertical agriculture for many years, as well as in multidisciplinaryly integrated youth science; they included practice teams at the front line of the root industry, as well as scientific teams focused on front-line technology。
Previously, four teams had completed the plant plant construction, equipment commissioning and test planting phases in accordance with their respective design programmes. Over the next six months, they will focus on high-yielding, high-quality, low-cost, low-energy-consumption dimensions, within 50 square metres of plant plants, around space utilization and energy consumption control, and redefinition of strawberry cultivation using technology. From this event, it was possible to see the vivid practices and explorations of intelligent agriculture towards industrialization, digitization and commercialization。
It's a ploughing space
Into a plant plant built by an ecological team, a group of groups were planted in an orderly discharge on a removable track, light from led lights was pouring on strawberries, environmental data such as humidity, light and so forth were shown in real time on the monitoring screen, and a “berries plant” full of technological sense was constructed。
“in the beginning, we designed plants with maximum yield and planting space, which theoretically accommodate over 7,000 strawberries. In practice, however, in order to balance the ease of post-maintenance and the comfort of the worker's work, it is decided to maximize the operating space by sacrificing some of the planting positions.” the chief of the proposed ecological team, ho xianyang, told journalists that after space optimization, the number of plantings was planned at 4,600, with a conservative estimate of 3,800 kg。
In the design of the construction, the cybernouns team abandoned the traditional tracks and adopted the skytrack model. “the orbit model effectively circumvents the effects of ground deposition or or orbital dusting on the operational sophistication of plant plants and makes them more stable. We have also introduced a mobile system to maximize the use of space while ensuring operational space by allowing flexibility to pull out or co-opt planting slots.” saibun team leader chen min hui said。
Teams are not only finely calculating in space use but also in strawberry quality. Chen min hui told reporters: “a prior assessment found that if planting density is too high, there will be competition between plants for nutrition, which will affect strawberry yields and quality. We therefore plan to keep only three fruits in each sequence and to ensure that a single strawberry weighs more than 30 grams, with the goal of pursuing a more extreme single fruit quality, through precise flowering management.”
Growing strawberries is only the first step, and how to control energy consumption is another level that the teams need to take。
Wang wanhai, team leader of the opp jigerberry team, said that plant energy consumption came mainly from lighting and air conditioning, accounting for about 70 per cent of total operating costs. The team began with energy-saving lighting, introduced off-grid photovoltaic energy storage systems and installed 24 high-efficiency panels in the top and southerly outer layers to transform solar energy into electricity, thereby effectively reducing energy consumption。
The berry cube team starts with the two directions of “efficiency” and “precision” and the system improves energy efficiency. Led light-efficient reflections to the crop surface on the inner walls of plant plants, through the use of retrospective film material from previous competitions, to increase the level of the light environment. Even growing on the edges of the plant, it fully absorbs light energy, so that each beam of light is “useful”. In the context of “precision”, the team uses independent switch controls for wind, air conditioners, dehumidifiers, etc., to achieve a single equipment accurate start-up and to allow electricity to be used accurately and efficiently at each degree。
Face the challenge and explore different paths
From november to december of last year, when design plans were put in place, plant plants were built, to january and april of this year, equipment was debugged and plant tested, and final teams were able to break through or find themselves in difficult circumstances, or dare not to challenge the search for new paths。
Captain he shiwei of the berry cube team is still remembering that “accidental” — the trial strawberries suddenly had a collide on the edge of the blades and yellow hair on their veins — “only the problem of uneven foliage, with several possible causes — air humidity, ambient temperature, water fattening, etc. We have to try one way and one way and one way and one way and the other. However, feedback from plants has been delayed, and it often takes a week or even longer for a rotation to test.”
It was this "accident" that made the strawberry cubes aware of the importance of quickly identifying strawberry disease. To that end, they have developed an image recognition smart diagnostic system — a system that captures the growth status of strawberry strains in real-time by cameras and is automatically compared to analyses, calculates the nitrogen and potassium content of the plant and rapidly produces targeted planting adjustment programmes to move from “experience decision-making” to “quantitative decision-making”. “in order to improve the accuracy of the image recognition smart diagnostic system, a large amount of photographic and video data is required to `feed'. Now the data have been collected for four months, reaching more than 90% accuracy.” he shiwei said。
Instead of choosing a matrix training model, the proposed ecological team uses the shallow flow model as the only team to select the model. What's shallow fluid fluoride? The judges of this competition, the head of the strawberry research team of the hangzhou institute of agricultural sciences and senior agronomist yu hong, explained to journalists: “in many ways, soilless cultivation takes the form of foundational training and deep and shallow fluid flow. The shallow flow is characterized by thin nutrient layers and challenging soilless cultivation.”
“the matrix, like a buffer pad, gives managers time to save. However, unlike shallow water flow, the internal environment itself poses a biological challenge to plants and, if not properly controlled, the environment changes `kills' the whole plant directly.” “the choice of shallow liquid currents is to use mature control algorithms to capture the two major technical difficulties of `nutrient deposition' and `physical coercion', and we hope to achieve a significant cost reduction through the elaboration of the plant plant plant model, which is the core of the technology to be demonstrated in this competition.”
It's coming out of the field
The central problem with the large-scale domestic application of plant plants is the high cost of hardware investment. “high input necessarily requires high output, but the current match between software and hardware is not yet ideal and challenges remain to achieve real quality, robust production and high productivity.” in the view of yu hung, technology cannot be written in a paper alone, speaking in practice and producing tangible products. The multi-agricultural science and technology contest is the bridge between the achievements of science and technology to the market。
Qin qing, the managing director of shanghai technology (shanghai) ltd., is responsible for commercialization in the qin qiancheng team, and she is very touched by the fact that agricultural science and technology has been transformed into a market: “the plant plant is the best option for china's strawberry industry to replicate on a large scale. The goal is not just to plant a perfect strawberries, but, more importantly, to explore a viable path to productive research and development.”
In conjunction with many years of industrial practice, qin shared three ideas for promoting the deeper integration of agricultural science and technology into industry: the first was to promote the diffusion of technology and “from the arena to the farm”. The enterprise can produce algorithms, models and inclusive adaptations that allow them to enter the fields of ordinary farmers. The second is to build data links and harmonize the discourse and discourse between industrial practices and frontier technologies. Providing a scientific basis for industrial upgrading through the accumulation of high-quality data sets. Third, the integration of talent and capital can be achieved only if technology and industry are truly integrated。
Beyond the arena, seeds of technological transformation have sprouted. A multi-channel spectral strip lamp developed by the opp jigerberry team in the course of this competition has been ordered by yunnan's merchant and will be used in a lighting test at the local planting site。
According to chen min hui, the core advantage of plant plants lies in the convergence of production and quality throughout the anniversary, and by increasing the premium capacity and output efficiency of strawberries, plant plants are expected to achieve real commercial profits and drive the overall development of the industry。
